One of the poorest countries in the region, Yemen is the only country in the Arabian Peninsula that is a signatory to the 1951 Refugee Convention and its 1967 Protocol. Since late March, the already severe conditions in the country substantially worsened with the escalation in the armed conflict. Up to 9 November, the World Health Organization has documented some 5,723 deaths and 26,969 injuries, including refugees and humanitarian workers, as a result of the conflict. However, as these figures are facility-based, the actual numbers are believed to be much higher. In Yemen, 21.2 million persons are in need of some form of humanitarian assistance, including access to food, health care and safe drinking water.
